I am planning to run an Ubuntu server as a mail server for our office. Our goal is to have an email server that connect to our web mail server and pull all the emails from server.
Our employee don't have access to internet but we need all of them use email.
I have recently taken over management of a server running centos and whm. It has several websites and domains running under reseller accounts. Email has always been on a server at our actual office. I have recently changed our email from our local email server to gapps for business (our local email server was pretty archaic).
We have a mail server which has Zimbra installed on it and a file server. Folks use the same login information they use to access their email to access the file server. So the file server is using the same LDAP server as the mail server.
Couple days ago, at around 12 PM all of the sudden, the SSH connection to the mail server failed. The mail server itself was up and running just fine.
I have bought new HP Proliant server, currently I have windows 7 installed, is it possible to use my server as web server or email server, and what tool would I need to do this? Please suggest any tutorial or something.
